DAEnetIP2 application examples
- Security and fire alarm systems
- Manual or automatic device restart if event occur
- Management/monitoring for industrial
- Sensor information processing
- Remote Lock/unlock doors
- Home automation
- Remote controlling electrical devices via relay boards over the network (please look at our store, we sell also sets: DAEnetIP2 + relay board)
DAEnetIP2 - control electrical device remotely
DAEnetIP2 - control electrical device remotely
DAEnetIP2 - watchdog function (automatic device restart if event (timeout) occur). For example routers, switches or servers can be restarted if no ping is detected during the timeout.
DAEnetIP2 I/O Ports
|"Free" - the pizn is free and defined for the user.||"XXXXXX" - the pin is reserved||"In" - the pin is input||"I/O" – digital input or output depending the settings||"Out" - the pin is output||"Ain"– analog input|
For inputs, if the input voltage exceed 3.3V, the controller may be damaged. If you have questions how to use the I/O ports please contact with us or take a look into the manual.
First, you will have to find suitable power supply adaptor (we sell power such adaptors, please look at our store). The minimal supply voltage is 7.5 VDC. The maximal voltage is 25 VDC. It is recommended the supply voltage to be 12 VDC. The power consumption is about 0.55 W.
The controller doesn't have any protection against inverted supply voltage. The middle pin of the power terminal is + Vcc - center positive tip polarity.
Here are the steps (instructions) how to power on and connect the device directly to your computer (see this image). For router LAN connection (see this image) or Internet connection, please see in the user manual:
Connect the DAEnetIP2 device with your computer via UTP crossover cable. (note that the device does not support AUTO MDIX - see here)
Supply with voltage in the allowed range. For example - 12VDC stabilized filtered power source.
Your initial computer IP should be in the device network. So it is recommend to be 172.16.100.1. Change it.
Open web browser and type 172.16.100.2 – default username/password are “admin”/”admin”
Now you can access all the parameters via your web browser
How to connect sensors to DAEnetIP2
More information how to connect different types of sensors to the DAEnetIP2 Analog Port -
The controller has default settings, in case the access is lost. There are several steps for loading the default settings:
Access via software DRMv3
This device is supported by DRMv3 Software.
The device can be found in the device list under the default name: DAEnetIP2v2
DAEnetIP2 Manager is configuration utility for Denkovi DAEnetIP2 controller
- Access many DAEnetIP2 controllers at a time
- SNMPv1 protocol
- Name for each controller
- Support most of the DAEnetIP2 OIDs
- Configurating each P3/P5 I/O line separately as input or output
- Linearization (scaling) for the Analog Inputs (displaying the analog inputs values in human reading values - volts, meters degrees)
- Thresholds can be converted automaticaly from human units into divisions

Access from Node-RED
Node-RED is a flow-based programming platform for the Internet of Things. We prepared small example for communication between Node-RED and our device. More info about Node-RED and denkovi modules: here
Access DAEnetIP2 from mobile devices
iOS App DAE-iModules
Android App DAE-aModules
The video bellow shows how you can control DAEnetIP2 based device - SNMP 8 Relay Board LM35DZ. Any other Denkovi Ethernet Device from this list can be acessed with same success from your iOS device via DAE-iModules.
Some useful information about DAE-aModules/DAE-iModules and DAEnetIP2:
- Select device DAEnetIP2. You must be sure the IP, UDP Port and SNMP community are correct, otherwise it won't enter into the device
- To connect and scale the analog inputs with sensors, please refer to this link: http://denkovi.com/connecting-analog-sensors-to-daenetip2.
Control via web browser
I/O Ports control/monitor
Traps/P5 control. DAEnetIP2 can send traps if some analog input changes its level bellow/above some threshold (Low/High).
The same logic can be used for setting one of the digital outputs port - JP5 according analog input port JP6.
HTTP API Commands
DAEnetIP2 i/o lines can be controlled/accessed via HTTP API commands and basic access authentication is required to do that.
The digital outputs (P3 and P5) can be controlled by sending this HTTP command:
var IO=new Array (0xFF, 0xFF, 0x80, 0x00AB, 0x0049, 0x0118, 0x014A, 0x012F, 0x003E, 0x0029, 0x01DD)
Control DAEnetIP2 via command line
Net-snmp is free command line utility for windows which allows you to execute snmp commands from command line, BAT files, BASH scripts or any other sofwtare that can execute external .exe file or commands from command line. The instructions file how to install net-snmp and example commands can be downloaded from here.

Please use DAEnetIP2 rev.2 firmware files only for DAEnetIP2 rev.2 modules and old DAEnetIP2 firmware files only for old DAEnetIP2 modules! The old and new firmware files are not compatible as there is hardware change from rev.2.
|Release Date||Firmware Version||Hardware revision||Mib File||Update Utility||Version History||Note|
|Nov 2017||6.28||DAEnetIP2 rev.2||Here||DAEnetIP Burner||Version History||Instructions how to update are in the User's manual or at this link.|
|Feb 2013||First hardware revison||Here||DAEnetIP Burner||Version History||Instructions how to update are in the User's manual or at this link|
|08 Nov 2017||
From 08 Nov 2017 we start shipping DAEnetIP2 with minor hardware changes (rev2). The new hardware is designed in a way to keep the compatibility however there are still small changes:
On the picture below it is shown how does it looks like the DAEnetIP2 rev2 module. You will see on the bottom side label with text "Rev. 2" which means that is DAEnetIP2 rev2 module, otherwise you have the old DAEnetIP2 module.
